1.1 This practice covers a procedure for preparing test specimens from basic refractory ramming products by pressing prepared material in a mold. Specimens prepared in accordance with this procedure are intended for use in ASTM test methods.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2.1 This practice defines a procedure that ensures consistent preparation of specimens for product testing and evaluation.

2.2 This practice can be used in the laboratories of producers, users, and general-interest parties for research and development or quality-control work. It is particularly useful for interlaboratory comparisons of products, for repetitive evaluations or comparisons of products or product quality, and in specifying a uniform preparation practice for specimens for acceptance testing.

2.3 In using this practice it must be recognized that the structure of laboratory-pressed specimens may differ significantly from the structure of material rammed in field applications.
